What is the correct method of removing a green screen background to insert a new digital background?

I am using Photoshop Elements 10 and can't seem to remove the green screen correctly. When I select the "magic wand" and click on the green screen background it selects it as it should. But when I hit the delete button on my keyboard it deletes the green background but a white background remains. So when I go to select my image to drag it to my digital background the white background goes with it.
In the tutorial video I watched it shows a grey and white checkered background after deleting the green screen which allows the user to select and move only the image to the new digital background. I am following the steps exactly but still can't seem to get it to work. Any ideas?

I don't know about 10 but in In PSE 8 there is a "Magic Extractor" ( ALT+SHIFT+CTRL+V) (on the mainu it's under Image ) which makes waaay too easy to seperate a selection from the background
http://help.adobe.com/en_US/PhotoshopElements/8.0/Win/Using/WS083AC514-D907-483b-84A1-4EA3 989C4C65_WIN.html
As already mentioned, the trick with the "background layer" is to right click on it in Layers and use "Layer from background"This will turn it into a "regular layer".
Then add a another new layer and on this new layer paste your cut-out you created earlier using the magic extractor.

Use setup assistant which is offered when you setup your new Mac. It will transfer information from a Time Machine backup, Clone or another Mac.
It's best to do this during setup to avoid issues with duplicate IDs.

What is The correct way to remove duplicates from the iTunes library?

I have a 300GB external drive which over the last 5 years has got bloated with duplicate tracks.
If I use the show duplicates option, I see 10,479 songs totalling over 50GB. Now, those songs that are shown, do they include the original that they are a duplicate of, or are they JUST the duplicates?
I have been sorely tempted to select all and delete to the trash, but I want to be 100% sure I don't delete any originals. Also, there are some duplicate tracks that are genuine dupes, for example, I have an original LP with a particular track on it, but then that exact track appears on a compilation LP, so I don't want to remove the compilation LP tracks as then the compilation is incomplete.
I have Tidy Up installed, but I'm a bit wary to use it as I want to be 10% sure I do the right thing, it's a lot of money to lose, and I'm a DJ, so this is thousands of conversions from my vinyl collection and stuff purchased and ripped from CD.
I see many methods of getting rid of duplicates but no definitive answer for someone in my position.
Many thanks all!

This is supposed to be a fix to the result from SQL. Currently no access to the SQL code so we have to fix in he Java code...Then really, whoever said you couldn't change the SQL has absolutely no right to turn around and demand the fastest way to remove the duplicates in Java. It's almost certain that the fastest way to remove the duplicates would be for the SQL not to select them in the first place, so if you don't permit changing the SQL then it's clear you aren't interested in the fastest way.

What is the correct method to configure PC3500 memories?

I am working with Neo2-LS.
Where exactly in the BIOS setting, I need to set the correct speed?
At the moment, it's working with 400MHz. instead of 433 MHz. as it should.
Thanks.

PC3500 or 433MHz only tells you that the RAM has been validated to run at that speed without problem. But now you're putting on a Springdale chipset system, of course it's running at 400MHz, the top speed supported by SpringDale chipset, unless you want to go further by overclocking the FSB which will indeed increase the RAM speed too.

Implmenting Reminders for a Notification - What is the correct method?

Hi,
I am trying to implement sending out reminders to a person who has a notification open.
A Manager(UserA) gets assigned a notification(NoteA) to approve/reject. After 7 days, he should get a reminder saying that NoteA is waiting for his decision. The way I implemented this is that after 7 days, the NoteA times out and sends out a new notification(NoteB).
However, the problem is that within 7 days, the UserA might have reassigned this NoteA to another Manager(UserB) for evaluation. So, when it times out, NoteB gets assigned back to UserA. Needless to say, UserA is now unhappy!
There was an example in the FAQ about implmenting reminders, but I beleive even if I implment the method suggested in the FAQ, I will end up with the same problem described above, since the reminder notifications will still go to UserA.
Would appreciate any help on the corrrect method to implment reminders. FYI- I am using standalone workflow.
Thanks
Dev

Dev, you could always write a post notification function which detected the REASSIGN and assigned the new performer to an item attribute, which would then be used as the performer for the reminder notification.

VMI: reduce Stock in transit - what is the correct method?

Hi Gurus,
We are using APO/SCM system to implement VMI functionality to replenish stock at customer location. We need to build stock in transit at customer location after PGI happens in ECC.
Now, stock in transit is show up in 'Stock in transit' key figure, but the question is how to reduce stock in transit once it is received at customer location.
SAP recommends following four methods to reduce:
http://help.sap.com/saphelp_scm2007/helpdata/en/f1/f69a3dcbcfac53e10000000a114084/frameset.htm
1. Goods receipt information is not sent from the customer to the vendor
2. The open purchase order quantity is sent from the customer to the vendor
3. A proof of delivery is sent from the customer
4. The stock in transit quantity is sent from the customer to the vendor
Out of these 1 and 2 methods are feasible in our scenario.
Please share your experience if you have used any of these methods, I want to hear from someone who implemented any of these methods before deciding on a method.
Thanks in advance,
Niranjan

After research and testing I found second method looks good to me. I tested in our test system, this works pretty much they way it is described in the help (link in above message) . The issue is resolved.

Zenphoto setup - what is the correct method for proper permissions?

http://www.zenphoto.org/
Permissions are "drwxr-xr-x 3 root root" for all directories mentioned
apache DocumentRoot is default of "/srv/http"
Zenphoto is extracted under http in a folder named "photos". When I initialize the Zenphoto setup in my web browser, I receive numerous errors that the setup php does not have write permissions within the "photos" directory.
The setup recommends setting 777 to all folders within and including the "photos" directory (zenphoto base).
I really don't want to set 777 permissions... Zenphoto setup doesn't complain if I set permissions to 775. But I am wondering if there would be less issues if I just set the "photos" directory recursively to the owner of "http"
Which would be best/proper?
Thanks!

I notice that if I do a repair permissions 2 or 3 times in a row that some of the same permissions are repaired again and again.
I assume you are referring to the log entries which contain "We are using special permissions..."
If so, you can safely ignore those messages. They are purely informational. This is not indicative of a permissions problem.
There is also no need to repair permissions while booted from the system DVD. Running it the way you are is fine, and you should only need to do it when you have a problem with your machine resulting from improperly set permissions.

What is the correct method of transfering music fi...

kindly instruct how to transfer music tracks from the pc to the phone n73? is it better way to transfer through mass storage or using nokia pcsuite-drag and drop to phone icon?

It depends as its posted above. You could also BT the files or use OVI files to put the files on the cloud and access them from your phone.
You can put the memory card in a card reader and load the songs that way.

What is the correct way to add styling to drag-and-drop created calendars?

I have a working instance of a rich client calendar. I generated the view with the required fields (start, stop, provider, ...), put it into the App Module, and dragged it onto a JSF page to create a calendar.
Next I created an activityScope object in a class called CalendarBean (no inheritance)
Class CalendarBean()
private HashMap<Set<String>, InstanceStyles> activityColorMap;
+..+
+public CalendarBean() {+
super();
activityColorMap = new HashMap<Set<String>, InstanceStyles>();
HashSet setEd = new HashSet<String>();
HashSet setLen = new HashSet<String>();
setEd.add("Work");
setLen.add("Home");
activityColorMap.put(setEd, CalendarActivityRamp.getActivityRamp(CalendarActivityRamp.RampKey.ORANGE));
activityColorMap.put(setLen, CalendarActivityRamp.getActivityRamp(CalendarActivityRamp.RampKey.RED));
+}+
+}+
Next, I linked this up as a backing bean and associated the ActivityStyles of CalendarBean to it:
+#{backingBeanScope.calendarBean.activityColorMap}+
I populated some records in the database with properties "Work" and "Ed', but they show default blue.
As I understand it, I need to do something with the getTags() method of the underlying CalendarActivity class, but I'm not quite sure how to do that.
Took a stab at creating a class, CalendarActivityBean, that extended CalendarActivity, and pointed all the CalendarActivity references I had to the new class, but it didn't seem to fire (in debug), and I got into trouble, when inserting records, with
public void calendarActivityListener(CalendarActivityEvent calendarActivityEvent) {
currActivity = (CalendarActivityBean) calendarActivityEvent.getCalendarActivity();
being an illegal cast
What is the correct way to add provider-based styling to drag-and-drop create calendars?
Ed Schechter

A colleague of mine was kind enough to solve this:
The calendar has ActivityStyles property = #{calendarBean.activityStyles}
CalendarBean looks something like this:
package com.hub.appointmentscheduler.ui.schedule;
import java.util.HashMap;
import java.util.HashSet;
import java.util.Set;
import oracle.adf.view.rich.util.CalendarActivityRamp;
import oracle.adf.view.rich.util.InstanceStyles;
+public class CalendarBean {+
private HashMap activityStyles;
private String dummy;
+public CalendarBean() {+
+// Define colors+
activityStyles = new HashMap<Set<String>, InstanceStyles>();
HashSet setPending = new HashSet<String>();
HashSet setArrived = new HashSet<String>();
HashSet setApproved = new HashSet<String>();
HashSet setCompleted = new HashSet<String>();
setApproved.add("APPROVED");
setPending.add("PENDING");
setArrived.add("ARRIVED");
setCompleted.add("COMPLETED");
activityStyles.put(setApproved, CalendarActivityRamp.getActivityRamp(CalendarActivityRamp.RampKey.GREEN));
activityStyles.put(setPending, CalendarActivityRamp.getActivityRamp(CalendarActivityRamp.RampKey.ORANGE));
activityStyles.put(setArrived, CalendarActivityRamp.getActivityRamp(CalendarActivityRamp.RampKey.PLUM));
activityStyles.put(setCompleted, CalendarActivityRamp.getActivityRamp(CalendarActivityRamp.RampKey.LAVENDAR));
+}+
+public void setactivityStyles(HashMap activityStyles) {+
this.activityStyles = activityStyles;
+}+
+public HashMap getactivityStyles() {+
return activityStyles;
+}+
+}+
Now, go into the Bindings tab on the calendar page, double click the calendar binding, and specify the column you've defined as the calendar's Provider in the Tags dropdown.
Should show colors.

1.4.2 - What is the correct way to format output in the java.io.PrintStream

With Java 1.4.2:
What is the correct way to format output in the java.io.PrintStream?
The following is incorrect, even though it is still used in the The JavaTM Tutorial at: http://java.sun.com/docs/books/tutorial/essential/
System.out.formatThis returns "cannot resolve the method 'format'"
Any detailed suggestions or information is greatly appreciated.

The following is incorrect, even though it is still
used in the The JavaTM Tutorial at:
http://java.sun.com/docs/books/tutorial/essential/
The whole format thing has been introduced in 1.5. The tutorial also states it's been "updated to 1.5.".
That's all I've got to say for I don't know how you can format a PrintWriter, let alone a PrintStream, prior to 1.5. I'm not really sure there is any way. Any "legacy way", that is. There almost certainly are third-party API which achieve similar results.

In the case of Fail-fast iterator, if a thread modifies a collection directly while iterating over it, the iterator will thow ConcurrentModificationException . Say,
for (Iterator it = collection.iterator(); it.hasNext()) {
    Object object = it.next();
    if (isConditionTrue) {
        // collection.remove(object); can throw ConcurrentModificationException
        it.remove(object);
}As per specs,
Note that this exception does not always indicate that an object has been concurrently modified by a different thread. If a single thread issues a sequence of method invocations that violates the contract of an object, the object may throw this exception. For example, if a thread modifies a collection directly while it is iterating over the collection with a fail-fast iterator, the iterator will thow this exception.

What is the correct procedure for upgrading to aperture 3.4

I am working in South Sudan and am shortly going to be in a place where I can download all the updates. The last time I did an update was around 2 weeks ago.
I presume that there will be updates for Mountain Lion, iPhoto and Aperture, plus a whole pile of iOS updates. From the support questions I see that there is a number of people having problems.
I presume that the first thing to do will be to rebuild the library of aperture.
What is the correct procedure after that?

If I do an upgrade through AppStore, and find it does not work, do I uninstall first by removing to trash? What do you mean by revert to an earlier version, and which previous version of Aperture should I use.
Neville,
So you did buy Aperture from the AppStore?
Then move the Aperture application to the Trash, but do not empty it, just in case
Sign into the AppStore and reinstall. In this case you do not need to revert to an earlier version. If the AppStore installer does not find an Aperture in your Applications folder, it will have to make a full install, and no incompatible frameworks should remain, as is the problem with the partial upgrades right now.
Yes, I have a bootable clone,
And have you checked, if you really can boot from your clone? Just being very cautious.
Do you use facebook? Some posters are having problems, even after reinstalling, if the want to publish to Facebook. Post back, if you encounter that problem.
Good Luck

What's the correct way to handle changes in RDBMS/DBadapter?

In my project all changes to the database are not done via Jdeveloper but via TOAD. This means DBadapters must be made aware of changes in the database.
I tried to re-run the DBad.apter wizard twice (2 different services) - to make it aware of changes in the DB. Both times it failed. I think was after the import database tab. The next tab was just blank.
So what's the correct way of reconile changes in the db backwards into Jdev?
BTW, in the DBadapter wiz its not possible the remove a already imported table. How do I come across the situation where I want the DBadapter to point to af different table? - and possibly remove old references to another one - which might have been removed in the DB.
As It is now - I have to re-work all my DBadapters, which is not very much fun...
Rgds, Henrik

Trust me, I hv done that umpteen nbr of times.
I hate BA's coming to me with changes, for which I hv to modify the DB adapter.
One big loop-hole with BPEL is if we try to modify the adapters/toplink, it doesnt tend to work properly.
The manthra for such modifications is ... "recreate", which is definetely not a good practise.
You may not like but gottu live with it, my friend.
Pointing to a different table, I achieve it by doing a "Shift+Delete" to all the references of the old table in the BPEL project ... :|
There isnt a specific provision in the wzd (I am not sure of the latest version, though).

What is the correct way to destory a Thread?

Just wondering what is the correct way to destroy a thread? I am currently using the stop() method, but i noticed that it has been depreciated (along with other methods used to destroy a thread) when i looked at the thread documentation. Since this is so, then how can one correctly destroy a thread? Thanks in advance for the help.

There is an awful lot of bad advice in this thread about what null does. Please in future check on your own with working code before offering up misguided and very wrong advice. Particularly when your advice contradicts that previously given.
Please compile and run the following
public class Test implements Runnable{
public static void main(String args[])throws Exception{
    Test test = new Test();
    Thread t= new Thread(test);
    t.start();
    // have delay wait a few seconds to demonstrate
    Thread.sleep(3000);
    System.out.println("Setting reference to thread to null");
    t = null; // what does this do?
    // jack all
    System.out.println("Exiting main");
public void run(){
    while(true){
      System.out.println("Hello from test thread!");
      try{ Thread.sleep(750); }catch(InterruptedException iDontCareAboutThis){}
}This will output the following
C:\>java Test
Hello from test thread!
Hello from test thread!
Hello from test thread!
Hello from test thread!
Setting reference to thread to null
Exiting main
Hello from test thread!
Hello from test thread!
Hello from test thread!
Hello from test thread!
Hello from test thread!
Hello from test thread!And continues on endlessly. Setting the reference to null is NOT an answer to this problem.
